Casey Clark is the daughter of Adam Clark and Crystal Clark and the identical twin sister of Sierra Clark.

My identical twin sister, Casey, was sitting on the edge of her bed, brushing her long red hair.

“Casey!” I exclaimed. She turned around to see me as I leapt onto her bed, her vibrant green eyes lit up with anticipation. “Are you excited?” I asked her.

“Are you kidding?” Casey asked, laughing. “It just gets more fun every year.”
